ALBERT N. BENDER, OF RAGINE, WISCONSIN.

CALE-WEANING- DEVICE' Application filed October 30, 1922. Serial No.597,850.

To all whom it may concern:

Be it known that I, ALBERT N. BENDER, a citizen of the United States,and resident of Racine, in the county of Racine and State of Wisconsin,have invented certain new and useful Improvements in Calf- WeaningDevices; and I do hereby declare that the following is a full, clear,and exact description thereof.

The invention relates to devices for preventing calves from sucking atthe udders of their mother.

It is in the nature of an improvement on the calf-weaning device, onwhich Patent No. 731,424 was granted to applicant on June 23, 1903. Inthe device of the patent, a pair of oppositely disposed pins are securedto a shield by means of a screw. In applicants device, one of these pinsis provided with an annular groove adapted to receive the ends of aretaining spring, which may be manually actuated to release the pin. Theobject of this construction is the facility of the securing of theshield to the nostril of the calf and the removal thereof.

The retaining spring is made of resilient wire formed at one end into aneye. This eye is held under a metallic strap and envelops a tube, theends of which are spread, whereby retaining collars are formed. Theobject of this construction is the efi'ective retention of the spring inplace and the strengthening of the structure, whereby the device isrendered dura ble. At the same time the construction is easy tomanufacture and cheap, being exceedingly simple and composed of aminimum number of parts.

With the above and other objects in view, which will appear as thedescription proceeds, my invention resides in the novel construction,combination and arrangement of parts, substantially as hereinafterdescribed and more particularly defined by the appended claim, it beingunderstood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claim.

In the accompanying drawing, I have.

illustrated one complete example of the physical embodiment of thepresent invention constructed according to the best mode I have so fardevised for the practical application of the principles thereof, and inwhich:-

Figure 1 is a plan view of the weaner.

Figure 2 is an edge view, partly in section, on line 22 of Figure 1.

Referring to the drawing, a represents the main portion or shield of mydevice,

which is preferably of a generally rounded contour with a horizontalupper rounded end centrally cut-out as indicated at b, and the two partsof the upper edge thus left each formed with a Hat upper surface a,above which are spaced pins d and e. The pin d is secured permanently inplace by a member 7 extending through the pin and secured by heads atthe end thereof in the wall of a cylindrical portion 9 of a strap itwhich straddles the shield and grips both sides thereof, being rigidlysecured thereto by rivets i. The shield at and the pins de arepreferably made of wood. The second strap j is provided with acylindrical portion is for the reception of pin 6. The strap is securedby rivets Z.

The pin 6 is provided with an annular groove m therein for the receptionof the end 'n of a spring, which is directed through an opening 0 in thecylindrical portion of the strap. In practice, the pin 6 is separatedfrom pin d and the device is then ap plied to the calf with the pin (2drawn into the animals nostril on one side up to the cartilage therein,and then the pin e is pushed back in the other nostrilto a likedistance, the end n of the spring snapping into the groove m and lockingthe pin 6 in.

position.

In this arrangement the shield a may offectually guard against the calfssucking, but will not in any way injure the animal. Obviously, theafiixationof the shield requires but a moment of time and isconveniently effected. The main stretch of the spring is substantiallyparallel to the surface of shield a, being bent at p to direct the endit inwardly. The lower end is formed into an eye 9 which envelops a tube1", the ends of which are spread forming col lars s and t. The collar tcontacts immediately with. the surface of strap 7', which is providedwith an opening 25 round which the spring is extended. Thus the strapexerts an efiective gripping action on the spring adjacent tube 1" andretains it securely in position.

A tube '0 functions somewhat similarly to tube 1' and secures the lowerends of strap 72. tightly against the shield a.

It is obvious that tube r effects diverse useful functions. It retainsthe lower ends of strap securely in position and also effectively gripsthe eye of the spring Thus a structure is provided which is strong anddurable and at the same time simple and easy to manufacture.

I claim A calf weaning device comprising a rigid shield having a centralopening in its up-' per edge, a pair of metallic strap members securedto said shield, adjacent said opening' and folded over the upper edgethereof and spaced therefrom, rivets passed through the ends of saidstrap members and through said shielos, a pair or" inwardl directed pinspositioned between the upper edge of said shield and said strap members,one of said pins being rigidly secured and the other of said pins havinggroove therein, a slot in the icorresponding strap member; adapt- 20 edto register: with said groove, a spring having an eyelet and securedbeneath the head of one or: said rivets and having an upwardly directedportion adapted to pass through said slot and into said groove, 25whereby said spin is releasably secured against inward or outwardmotion.

In testimony that I'claim the foregoing l'have hereunto set my hano atRacine, in the countz, of Racine and State of vViscon- 30 sin. 7
